In simple words: Whooping cough with pneumonia is a serious respiratory infection that causes severe coughing fits and difficulty breathing. It is caused by bacteria called Bordetella pertussis and is especially dangerous for babies and young children.

Whooping cough, also known as pertussis, is a highly infectious bacterial respiratory disease most commonly caused by Bordetella pertussis. It is typically spread by person-to-person contact or airborne droplets when an infected person coughs or sneezes.The disease is characterized by whooping sounds on breathing after bouts of coughing, mainly in infants and young children, but can affect individuals of any age. This code is specific to B. pertussis-caused whooping cough with pneumonia (lung infection).

Example 1: A 3-month-old infant presents with paroxysmal coughing, followed by a "whooping" sound during inspiration. A chest x-ray reveals pneumonia. Laboratory tests confirm Bordetella pertussis infection., A 5-year-old child with a history of coughing for several weeks develops difficulty breathing and high fever. A chest x-ray shows evidence of pneumonia, and Bordetella pertussis is identified through PCR testing., A 70-year-old adult with a chronic cough develops worsening symptoms, including fever and shortness of breath. Imaging studies reveal pneumonia, and laboratory tests confirm Bordetella pertussis infection.

Documentation should include symptoms (cough, difficulty breathing, fever, whooping sound), physical exam findings, laboratory results (culture, PCR), and imaging results (chest x-ray, CT scan). The documentation should confirm the presence of both whooping cough caused by Bordetella pertussis and pneumonia.
